H O R S E S H O SPECIFICATION forming part of Letters Patent No. 631,751, dated August 22, 1899. Application filed December 30, 1898. Serial No. 700,692. (No model.)

To aZZ whom it may concern:

Be it known that I, ELMER POWELL, a citizen of the United States, residing at Dayton,

-in the county of Montgomery and State of and to the figures of reference marked thereon, which form a partof this specification.

My invention relates to improvements in horseshoes. V V

The object of the invention is to provide a horseshoe with heel and toe calks that are easily attachable and that when in position will not become detached through the effect of wear or usage.

In the following description the essential features of the invention will be made clear. Preceding said description reference is made to the accompanying drawings, of which Figure 1 is a view of the lower side of a horseshoe made in accordance with my invention. Fig. 2 is a view of one of the heels with its calk detached. Fig. 3 is a section on line a a, Fig. 1. Fig. 4 is a view of the toe with the toe-calks removed. Fig. 5 is a section on line b b, Fig. 4. Figs. 6 and 7 are lower side end and side elevations, respectively, of a toe-calk.

As is apparent from the drawings, in carrying out my invention I use two steel toecalks 1 and 2, which have dovetail slots 3 in their lower sides with an intervening wall 4. The said slots 3 extend through to the inner end of the calk, but on the outer end said slots terminate in some distance to provide an end wall 5, which conceals the connection of the calks with the shoe and serves to limit the inward movement of the calks when placing them in position on the tapering elongated spurs or flanges 6 6. These spurs or flanges taper inwardly to provide a dovetail recess or slot 7 between them. They are integral parts of the shoe. When the shoe is made, there is left at the points where these spurs are formed a sufficient thickness of metal to plane down and form said spurs.

The shoe is placed in a shaper and cut down, leaving the spurs, as shown in Fig. 4, the metal between and adjacent to said spurs being reduced to the common thickness of the shoe.

It will be observed that there are two sets of spurs or flanges 6 6 with an intervening space 7 between their inner ends in the center of the shoe. Over and into this space 7 the two toe-calks project and form practically one toe-calk across the toe of the shoe. This is an important feature of theinvention, as it is well known by those who are at all familiar with the art of horseshoeing that in fitting the shoes it becomes necessary to contract or expand the shoes to a greater or less extent to accommodate the feet of different horses. This in cases where a single calk is used at the toe renders it difficult or impossible to place said calk at all or to place it in a position to hold. This difficulty is overcome by providing the two dovetail slots one on each side of the center of the toe and having the two calks at that point extending across the toe, but being free to move when the shoe is contracted or expanded. One of the toe calks, it will be observed, has a rounded projection 8 on itsinner end extending throughout its depth, while the other has a recess 9 of similar extent in its inner end, into which said part 8 fits when the two calks are placed in position. This forms a knucklejoint, upon which the inner ends of the calks may turn when the shoe is bent, as hereinbefore indicated, without the said ends becoming entirely disconnected or rather out of contact with each other. When said calks are in position, the spurs 6 6 fit into the slots 3 3 in the calks and thus become closed on both sides by the walls ,10 and 4, and the connection is such as to make it impossible for the calks to become detached from pressure exerted thereon against either side. In order to secure said calks against endwise movement in the slots, the spurs 6 6 are provided with recesses 11 11, extending into their edges. A pin 12 is passed through an opening in each calk and lies in the recess 11. In detaching a calk to be replaced with a new one this pin is driven out and the calk is forced out of position endwise.

. shoe having two dovetail slots at the toe with The above description is directed mainly to the toe-calks; but it Will-be seen that the heel-calks are formed and attached in substantially the same manner, the only difference being in the single calk at the heel.

The spurs or flanges are cut into the heels in the same way. The calks may be attachedtd the shoe before the latter is putonthe horse, and the operation of putting it on the horse does not necessitate a removal of the said calk. This is owing to the toe-calk being in two pieces, as described, and not interfering with the necessary bending of the shoe,pre paratory to putting it on the horse.

It might be possibleto transpose the posi-' tions of the spurs 6 and slots 3-that is to say, the spurs 6 might beplaced on the calksi; 1 and 2 and the slots 8 on the shoe. Also i the intervening space 7 might not be en-? tirely closed up by the calks. Thec0ns=truc-=' tion, however, hereinbefore described is considered preferable.

Having described my invention, I claim- 1. In a horseshoe, the combination with ai shoe having two dovetail slots formed in the toe, with an intervening spacebetween the inner ends of said dovetail slots, of two toecalks engaging with said slots andfilling the space between said-slots, substantially as and for-the purposes specified. I

2. In a-horseshoe, the combination with a an intervening space between said slot, two calks adapted to fit in said slot with theiri inner endsprojected into said intervening space, and pins penetrating said calks and the walls of the dovetail slot to prevent endwise movement of the calks, substantially as and for the purposes specified.

3. In horseshoe, the combination with a shoe having two'dovetail slots at the toe sepyarated'byia'fiat surface, of two calks engaging with said slots and filling the space be tween them, the said calks having their inner walls of said slots being integraliparts 0fthe shoe, calks havinggrooves cut therein adapt ed to fit said -slots,-the calksr atthe toe being longer than theslots rat 'snch point soithat 'theyinay extend-over and occupy-the space between said toe-slo1ts,-:and means for holding said calk-s from moving rendwise,'-as shown .and described.
